Costco made $3.7 million selling 2,500 diamond rings falsely identified as "Tiffany," the Washington Post reported, citing a 2015 verdict. Costco argued that the diamond rings had a pronged setting known as "Tiffany," but the jewelry company argued the store's use of the stand-alone name without any modifiers was misleading to customers.

U.S. District Judge of the Southern District of New York Laura Taylor Swain ruled Monday that Costco should pay Tiffany $11.1 million to make up for lost profits and $8.25 million in legal damages, the Post reported.
